AFE Pro-5R Si Cold Air Intake

The aFe Stage 2 sealed cold air intake outflows factory intakes resulting in increased horsepower and torque. These air intake systems feature a washable/reusable conical air filter, dyno tested intake tube, and fully enclosed molded plastic housing.

With five layers of progressively finer mesh cotton gauze media between 100% polyurethane top and base, this high flow oiled conical performance filter provides excellent airflow for maximum horsepower and torque. The intake tube is designed to maximize air velocity and is dyno tested and flowed using the latest engineering tools for maximum performance, mileage and throttle response.

The sealed rotomold plastic housing keeps hot engine air out and allows for a cooler, fresher, denser air intake charge.
